So INSTALLED_APPS is a bit of magic. It's used by various things in
django to load resources. Eg:
When you run syncdb, Django installs models from app.models for each
app in INSTALLED_APPS
The templating system, templates and custom template tags are
searched for in each of the apps in INSTALLED_APPS
Management commands are loaded by searching
app.management.commands.<commandname> for each app in INSTALLED_APPS
The admin site discovers the models it knows about by loading
app.admin from each app in INSTALLED_APPS

I'm probably missing some..

You can make your project directory an app if you wish. My golden rule
is "an app is a module that provides any of models, templates,
template tags, admin or management commands".

I keep them separate to avoid confusion, so I will have a 'site' app
that provides the homepage/similar views, site specific models,
templates and so on, and a separate 'project' module that just
contains the settings, the top level urlconf and DB routers.
